Abstract heap types for GC reference types.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Func

The abstract func heap type (any function).

Extern

The abstract extern heap type (external/host references).

Any

The abstract any heap type (any internal reference).

None

The abstract none heap type (bottom type for internal refs).

NoExtern

The abstract noextern heap type (bottom type for external refs).

NoFunc

The abstract nofunc heap type (bottom type for function refs).

Eq

The abstract eq heap type (comparable references: i31, struct, array).

Struct

The abstract struct heap type.

Array

The abstract array heap type.

I31

The abstract i31 heap type (31-bit integers).

Exn

The abstract exn heap type (exceptions).

NoExn

The abstract noexn heap type (bottom type for exception refs).

Trait Implementations

impl Clone for AbstractHeapType

fn clone(&self) -> AbstractHeapType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AbstractHeapType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for AbstractHeapType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Into<AbstractHeapType> for AbstractHeapType

fn into(self) -> AbstractHeapType

Converts this type into the (usually inferred) input type.

impl Ord for AbstractHeapType

fn cmp(&self, other: &AbstractHeapType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AbstractHeapType

fn eq(&self, other: &AbstractHeapType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AbstractHeapType

fn partial_cmp(&self, other: &AbstractHeapType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<AbstractHeapType> for AbstractHeapType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(ab_heap_type: AbstractHeapType) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for AbstractHeapType

impl Eq for AbstractHeapType
